While some people have compared the primary effects of phenibut to that of a light dose of GHB or MDMA, it’s really just an effective anti-anxiety, antidepressant medication, with few side-effects and remarkable health benefits.

Phenibut gives some users the sensation of mild euphoria, tantamount to a mild “high”. As such, it can be abused if not used correct. Yet, the euphoric phenibut high is not intense, and taking more of it doesn’t intensify the high.

Personally, I’ve found that phenibut works most consistently when taken on an empty stomach, and I feel it’s effects in around 15 or 20 minutes.

However, it takes longer for most people to feel the effects.

People generally report that the effects start to kick in around 1 or 2 hours after oral ingestion, and then the primary effects usually last for around 4 or 5 hours, although pleasant lingering effects can last for another 24 hours.
